Application filed July 13,

T 0 all 10 7mm it may concern:

Be it known that I, EDWARD L. VI-UTE, a citizen of the United States. and resident of the borough of Brooklyn, city and State of New York, have invented a new and useful Improvement in Spring Heels, of which the following is a specification.

My invention relates to that type of spring heel which is to be inserted into boots or shoes to act as a cushionand support for the heel and instep of the foot of the wearer.

The object of my invention is to provide certain improvements in the construction, form and arrangement of the several parts whereby the device can be made extremely light and strong, and in which means are provided for adjusting the tension of the spring.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Fig. 1 represents my improved spring heel in side elevation.

Fig. 2 represents a bottom plan View of the spring heel with the spring adjusted to one tension.

Fig. 3. represents a similar view with the spring adjusted to another tension.

Fig. 4 represents a section taken in the plane of the line IVIV of Fig. 2.

Fig. 5 represents a section taken in the plane of the line V-V of Fig. 3.

The spring heel generally comprises the heel plate 1, the coil spring 2, the flexible covering 3 and the pivoted clip 4.

The heel plate 1 is concaved to fit the heel and it is also provided with peripheral depending flanges for materially strengthening the heel plate and permitting the same to be made of very light and rigid material, such as aluminum for instance.

The front depending flange is denoted by 5 and the side and back depending flange by 6. The coil spring 2 is secured at its upper end to the bottom of the heel plate 1 at two points 7 and 8, between which points the spring is distorted slightly as shown at 9 to hold the spring against displacement. These points of attachment 7 and 8 may be U- .shaped rivets having their ends flush with the top surface of the heel plate 1.

The flexible covering 3 of leather or other suit-able material covers the top of the heel plate 1 and projects forwardly therefrom for a considerable distance toward the depending flange 5, the forward end of which cover- Specifieationof Letters Patent.

ing being provided with means such as tacks 10 for attaching the flexible covering to the arch portion of the boot or shoe. This flex- "ible covering 3 is secured to the forward portion of the heel plate 1, as for instance by rivets 11.

The clip 4 is pivotally mounted on the shank of a. screw 12, which screw depends from the central portion of the heel plate 1. A nut 13 is provided for clamping the clip in any of its adjusted positions. This clip is provided at its outer end with a recessed portion 14 arranged to embrace the coil spring 2 and travel along the same as the clip is rotatively adjusted for varying the tension of the spring. 1

From the above description it will be seen that I have provided a spring heel which is very light and strong and one in which the tension of the spring may be very readily adjusted to suit different requirements.

It will also be seen that by so arranging the lower end of the spring with respect to the heel plate as to normally maintain the heel plate in substantially horizontal position, I am enabled to provide a spring heel which will support the heel and instep of the foot of the wearer in a much more natural and comfortable position than when the heel plate is positioned at a considerable angle away from the horizontal position.

It is evident that various changes may be made in the construction, form and arrangement the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the particular embodiment herein shown and described, but

What I claim is 1. A spring heel including a heel plate, a coil spring secured to the bottom of the heel plate, and means for adjusting the tension of the spring comprising a clip pivoted to the bottom of the heel plate, the free end of the clip being movable along the spring.

2. A spring heel including a heel plate, a coil spring secured to the bottom of the heel plate, means for adjusting the tension of the spring comprising a clip pivoted to the bottom of the heel plate, the free end of the clip being movable along the spring, and means for securing the clip in its adjusted position.

3. A sprin heel including aheel plate and a coil spring iaving its upper end secured at 4. A spring heel including a heel platehaving peripheral depending strengthening flanges, said plate being conoaved to fit the 10 heel of the foot of the wearer, a coil spring I secured to the bottom of the heel plate, and means for adjusting the tension of the spring.

In testimony, that I claim the foregoing 15 as my invention, I have signed my name this 5th day of July, 1921.
